Margarite,

You need to check with your Disabilities Department. They may be able to arrange a more favorable situation for your thesis. You need the confrontational nature of your defense limited. You also need some time to Stop and Think. You may need to live like a cloistered nun during your last few weeks. An environment of total peace and quiet will help you prepare.

Have you talked with your instructors about your current symptoms? Maybe they can come up with some accommodations for your last few weeks and assignments.

I wish I had more to offer. I went through the same struggle and ended up not finishing a degree.

My best to you.
